Premium PBR Textures for Real-Time Engines
From solo creators to multi-discipline pipelines, our 4K and 8K tileable assets integrate directly into modern material workflows.
Teams of 1 to 5 artists use GrainStack to bypass week-long photography trips. You get pre-baked roughness masks, seamless albedo maps, and OpenEXR height data ready for Unity HDRP and Unreal Engine 5. Typical load times drop by 40% when swapping our optimized 2048x2048 variants into your asset bundles.
Explore Indie PacksLead technical artists at studios like Obsidian Reach and Vertex Forge rely on our consistent UV layouts and physically accurate IOR values. Our bulk licensing covers full engine integration, including custom Substance Designer nodes and automated material graph generation for 50+ concurrent workstations.
Request Studio LicenseAEC firms use GrainStack for photorealistic client presentations in Lumion and Twinmotion. Our concrete, timber, and marble sets include accurate scale markers and non-destructive tiling parameters, allowing interior designers to swap floor finishes in under 30 seconds without breaking shader connections.

Studio: Parallax Line Games. Challenge: Needed 120+ seamless wet asphalt and neon-reflective metallic surfaces without exceeding 2GB mobile memory limits. Solution: Implemented GrainStack's compressed DXT5 normal maps and merged albedo channels. Result: Maintained 60 FPS on mid-tier Android devices while achieving studio-grade specular response.
Studio: ArcView Design Group. Challenge: Client demanded photorealistic interior finishes for a 40-story virtual tour using Unreal Engine 5 Nanite. Solution: Deployed GrainStack's 8K architectural stone and brushed steel packs with embedded displacement data. Result: Cut texture baking time from 14 hours to 45 minutes and eliminated visible seams in 4K viewport renders.
Studio: Bramblewood Interactive. Challenge: Create biologically accurate moss, peat, and weathered hardwood for a 50km² procedural landscape. Solution: Integrated GrainStack's tri-planar projection ready sets with custom alpha blending. Result: Reduced artist blockout time by 65% and achieved consistent micro-surface scattering across all lighting conditions.
